The Siemens 5SL4450-7RC is a SENTRON 5SL4 miniature circuit breaker (MCB) designed to provide dependable protection against overload and short-circuit conditions in suitable electrical installations. This MCB features a 50 A rated current, 4-pole configuration, C tripping characteristic, 415 V rated voltage and 10 kA short-circuit breaking capacity, making it suitable for appropriately designed industrial, commercial and electrical distribution applications.
The Siemens 5SL4450-7RC 50A 4-pole MCB is designed for electrical circuits requiring reliable overcurrent protection along with coordinated protection and switching across four poles. Its C tripping characteristic is generally suitable for general-purpose circuits where moderate starting or inrush currents may occur. This makes the device suitable for a broad range of electrical distribution, control, machinery and equipment-protection applications.
The 4-pole configuration provides coordinated protection and switching for compatible multi-phase electrical systems. It can be integrated into electrical distribution boards, industrial control panels, electrical switchboards, machinery panels and OEM assemblies where four-pole circuit protection is required.
With a 50 A rated current, the 5SL4450-7RC is suitable for appropriately designed higher-current circuits. Proper coordination between the MCB rating, connected load, conductor capacity and upstream and downstream protective devices is important for safe and reliable operation.
The 10 kA short-circuit breaking capacity provides the specified fault-interruption capability for suitable installations. The prospective short-circuit current at the installation point should always be assessed before selecting the MCB to confirm that its breaking capacity is appropriate for the electrical system.
As part of the Siemens SENTRON 5SL4 series, the 5SL4450-7RC provides a compact modular circuit protection solution for professional electrical installations. It can be considered by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams requiring Siemens circuit protection products.
The Siemens 5SL4450-7RC 50A 4-pole C curve MCB can be considered for:
The Siemens 5SL4450-7RC provides dependable circuit protection for applications requiring a 50 A, 4-pole MCB with C characteristic and 10 kA breaking capacity. Its C tripping characteristic makes it suitable for many general-purpose electrical circuits where moderate starting or inrush currents may occur during normal equipment operation.
The 4-pole configuration provides coordinated protection and switching for compatible multi-phase circuits. This makes the device suitable for installation in electrical distribution boards, industrial control cabinets, machinery panels and switchboards where four-pole protection is required.
The 50 A rated current makes the 5SL4450-7RC suitable for appropriately designed higher-current circuits. Proper matching of the MCB rating with the connected load and conductor capacity helps provide effective protection against excessive current.
The 10 kA short-circuit breaking capacity provides the specified capability to interrupt suitable short-circuit fault currents. The prospective short-circuit current should always be checked to confirm that the MCB is appropriately rated for the intended electrical installation.
The C characteristic provides a practical solution for general-purpose electrical loads with moderate inrush currents. It can be considered for suitable distribution, control and equipment circuits where the expected startup current is compatible with the C curve.
The 415 V rating supports use in compatible AC electrical distribution systems. This makes the device suitable for a range of industrial and commercial panel applications where the voltage, current and tripping characteristics match the system requirements.
The Siemens SENTRON 5SL4 series offers a modular solution for professional circuit protection. The 5SL4450-7RC can be considered for OEM panels, industrial automation systems, machinery, commercial distribution boards and electrical switchboards.
